STEM \NiNDlNG AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 408,274, dated August6, 1889.

Application filed March 30, 1889. Serial No. 305,435. (No model.)

To aZZ whom it may concern:

:le it known that I, ALBERT TROLLER, residing at Rockford, in the countyof VVinnebago and State of Illinois, and a citizen of the United States,have invented a new and useful Improvement in Stem \Vindin-g and Setting\Vatches, of which the following is a specification, reference being hadto the accompanying drawings, in which Figure l is a plan showing theinside of the top plate and thebarrel-bridgeinacase. Fig.

2 is a plan showing theinside of the top plate.

Fig. 3 is aplan showing the outside of the top plate and the winding andsetting mechanism in view. Fig. at is an under side view of thebarrel-bridge. Fig. 5 is a perspective of the barrel-bridge and someother parts. Fig.

0 is a sectional view at line 6 of Fig. 1. Fig.

7 is a section at line 7 of Fig. Fig. Sis the same as Fig. '7, showingsome of the parts in a diiferent position. Fig. 9 is a detail, being asection of the parts shown, taken at line 9 of Fig. Fig. 10 is the sameas Fig. 9, the

parts being in a different position. Fig. 11 is a detail, being anelevation of the shiftinglever a and its spring. Fig. 12 is asection atline 12 of Fig. 11. Figs. 13 and 14 are details, being views of theswitch-arbor. Figs.

1 to 7, inclusive, are somewhat enlarged.

Figs. 8 to 14, inclusi e, are about three times full size.

lVinding and setting devices which can be brought into position andoperated by a longitudinally-inovable stem-arbor or stem-key are common,and cases for movements eontaining such devices are called pendantsetcases. A stem-key which is not longitudinally movable is frequently usedfor winding and setting, the setting devices being brought into positionby a lever operated by hand, and cases for movements containing suchdevices are known as lever-set cases.

The leading objects of my invention are to provide improved devices bymeans of which a stem-driven train in a pendant-set case can be broughtinto engagement either with a dial-wheel or the winding-wheel atpleasure,

and to provide awatch-movement containing the said improved devices,with devices which adapt it to be used in an eXclusivelylever-set caseas well as in a pendant-set case, which I accomplish, as illustrated inthe drawings and hereinafter described.

That which I claim as new will be pointed outin the claims.

In the drawings, A represents a portion of the center band ofawatch-case provided with a pendant and a longitudinally-movablestemarbor, which may be con stru cted in any known suitable manner, andtherefore I have not shown or described them in detail.

B is the top plate.

O is the barrel-bridge. The upper plate is not shown; but it and thebarrel-bridge are both supported by the plate B. The two plates arerecessed on theirinsides to receive the train. This construction,however, is made the subject of another application, and therefore theseparts will not be here more fully described.

E is the stem-arbor or stem-key.

F is a yoke pivoted upon a hub and held by a cap and screw, as usual. Atone end of this yoke there is a wheel G to engage with a Wheel attachedto the mainspring-arbon At the other end of the yoke is pivoted anotherwheel H, which can be made to engage one of the dial-wheels. These twowheels G II are driven by an intermediate wheel, which is driven by thepinion I, as usual, which pinion is upon the piece which receives theinner end of the stem arbor or key, and is supported in the sleeve 'r,which is supported in a bearing formed in the barrel-bridge and plate B.8 5

a is the lever that shifts the yoke when the movement is used in apendant-set case. One

end of this lever is pivotally secured at 1) upon a wall formed in thebarrel-bridge. The other end is free. 0

c is a spring, which, as shown, is made integral with the lever a.

(l is a recess or groove in the lever a.

e is a pin which serves the purpose of a stop. 5

f is a pin, which is secured to the yoke F and passes through a slot orhole in the plate B and projects beyond the inside of such plate. Theend of this pin is beveled, and it is so arranged that the free end ofthe shifting-lever Ct can come in contact with and pass over suchinclined end.

g is a sliding pin with which the inner end oi the stem arbor or key cancome in contact to push itinward. The inner end of this pin is beveledand arranged to engage with a bevel r on the edge of; the lover a. (SeeFig.

71 a switch-arbor, one end of which supported in the plate I). The otherend passes through the barrel-bridge, and is provided with a notch toreceive a screw-driver for the purpose of partially rotating the same.

i a pin which passes through the arbor h and projects from oppositesides thereof. One end of this pin is beveled to facilitate its passageinto the groove (1 in the lever to.

J is a lever for the purpose of moving the yoke, so that the wheel IIwill. engage with the dial-wheel. This lever is pivoted at j, and isprovided with an arm 7.:, which can be made to act upon the yoke bydrawing out the arm. Z at the other end of the lever. This lever is notdesigned to be used when the movement is .in a so-called pendant-setcase; but it is for use when the movement used in aleverset case.

In Fig. 1 are two letters P and L. \Vhen the notch in the switeluarborhis in line with the letter 1, the movement is adapted :l'or use in thependant-set case. \Vhen such notch in. the switch-arbor is in line withthe letter 11, the movement can be used in a leverset case, as will behereinalfter more t'ully described.

s is a spring which acts on. the yoke F.

t is a spring which acts on the lever J.

The operation is as follows: Suppose the movement to be in a pendant-setcase, the switch-arbor 71. being in the position shown in Figs. 1 and land the stem-arbor pushed in as shown in Fig. 8, which will force thebew eled end of the sliding pin g over the incline r on the edge of thelever (I. Then the free end of the lever will be forced away fromtheplate B and pin and the spring 5 willbring the yoke into such. positionthat the wheel G will engage with the windingavheel attached to the1nainspring-arbor, which is the normal position. of the parts, as shownin Fig. 10. It now the stem-arbor be withdrawn a littie, as shown inFig. 7, the action. of the spring a will cause the free end of the lever(I to pass over the incline upon the end of the pin f, as shown in Fig.9, which will force the yoke into such position that the wheel It willengage with one of the dial-wheels, ready for set-ting. By again pushingin the stemarbor the free end of: the lover a willbe again carried awayfrom the pin 1'', and by the action of the spring .3 the wheel G will beagain brought into engagement with the windingwheel. It will be observedthat the shiftinglever a works at right angles to the stem-key.

If it be desired to use the movement in a lever-set ease, the lover acan permanently be brought out of action by turning the switcharbor 71.until the notch in the end l'llOl'OOii comes in line with. the letter L,which will cause the beveled end. of the pin i to enter the groove (Z inthe lever (t, which will early the free end of such. lever (t away fromthe plate 13, bringing such lover a into an inoperative position, andthen. the spring s will bring the yoke into the 'msition in which thewheel G will. be in engagement with the winding-wheel. The inclined endof the pin 1'. in the switch-arbtn: comes in. contiiwt with the switch cwhen the switch-arbor is in the position which it is to occupy when themove ment to be used. in a le\"e1.'setease, and the other end of suchpin '1' comes in COlliflUi] with the same stop whenthe switeh-arbor isin the position which it is to occupy when the movement is to be used ina pendant-set case.

3y means of. the lever J the position of the yoke can be shifted,bringing the wheel ]I' into engagement with one of the dial-wheels,ready for setting.

\Vhat I claim as new, and desire to secure by Letters Patent, is asfollows:

1. In a stem winding and setting watch, a lever o acting at right anglesto and ai'lapted to be acted on by a stenrlcey, in combinal ion with. apinfon theyolce F, which pin passes through a slot or hole in the platel and is arranged to be acted on by the shifting-lever, substantially asand for the purpose speci fied.

2. In a stem winding and setting watch, a stem-key having a beveledpoint, in combination with shitting-lever (I, with one edge of which thestein-key engages, aspring s, and a pinf, connected with the yoke F,which pin passes through the plate .13, and is arranged to be acted onby the shifting-lever (I, substantially as and for the purpose s j(.a.:ilicd.

3. In a stem winding and setting watch, the combination of aswitch-arbor 71 with the shifting-lever a, for the purpose oi. holdingthe lever a out of action when. desired, where by the same movement isadapted to be used either in a pendant-set case or .in an exclusivelylever-setease, substantially as spcci lied.

In a stem winding and. setting watch, a switch-arbor 71, provided with apin 1', in combination with a shitting-lever (I, provided with a groove(7, substantially as and (or the purpose specified.

5. In. a stem winding and setting watch, a shifting-leveru, incombination with a switcharbor 71, ctnistructed and arranged as doscribed, whereby such switch-arbor van be operated from the onlsideotlhe plate ll, snhstantially as speeiliml.
